2005 National Profile of Local Health Departments

Changes in public health workforce composition: proportion of part-time workforce and its correlates, 2008-2013

BACKGROUND

State and local public health department infrastructure in the U.S. was impacted by the 2008 economic recession. The nature and impact of these staffing changes have not been well characterized, especially for the part-time public health workforce.

PURPOSE

To estimate the number of part-time workers in state and local health departments (LHDs) and examine the correlates of change in the part-time LHD workforce between 2008 and 2013.

METHODS

We used workforce data from the 2008 and 2013 National Association of County and City Health Officials (n=1,543) and Association of State and Territorial Health Officials (n=24) profiles. We employed a Monte Carlo simulation to estimate the possible and plausible proportion of the workforce that was part-time, over various assumptions. Next, we employed a multinomial regression assessing correlates of the change in staffing composition among LHDs, including jurisdiction and organizational characteristics, as well measures of community involvement.

RESULTS

Nationally representative estimates suggest that the local public health workforce decreased from 191,000 to 168,000 between 2008 and 2013. During that period, the part-time workforce decreased from 25% to 20% of those totals. At the state level, part-time workers accounted for less than 10% of the total workforce among responding states in 2013. Smaller and multi-county jurisdictions employed relatively more part-time workers.

CONCLUSIONS

This is the first study to create national estimates regarding the size of the part-time public health workforce and estimate those changes over time. A relatively small proportion of the public health workforce is part-time and may be decreasing.

Factors driving the adoption of quality improvement initiatives in local health departments: results from the 2010 profile study

BACKGROUND

Over the past decade, quality improvement (QI) has become a major focus in advancing the goal of improving performance of local health departments (LHDs). However, limited empirical data exists on the current implementation of QI initiatives in LHDs and factors associated with adoption of QI initiatives.

OBJECTIVES

(1) To examine the current implementation of QI implementation initiatives by LHDs and (2) to identify factors contributing to LHDs' decision to implement QI initiatives.

METHODS

In this study, a novel theoretical framework based on analysis of QI in medicine was applied to analyze QI by LHDs. LHDs' QI adoption was assessed by the number of formal QI projects reported by LHDs that responded to module 1 of the 2010 National Profile of Local Health Department Study (Profile Study) conducted by the National Association of County & City Health Officials. The Profile Study data were merged with data from the Health Resources and Services Administration's Area Resource Files and the Association of State and Territorial Health Officials' 2010 Survey. Logistic regression analyses were conducted using Stata 11 SVY procedure to account for the complex sampling design.

RESULTS

The Profile Study data indicated that about 73% of the LHDs reported implementing 1 or more QI projects. LHDs with large jurisdiction population (>50 000), higher per capita public health expenditure, a designated QI staff member, or prior participation in performance improvement programs were more likely to have undertaken QI initiatives.

CONCLUSION

According to the Profile Study, more than a quarter of LHDs surveyed did not report implementing any formal QI projects. Greater investments in QI programs and designation of QI staff can be effective strategies to promote QI adoption. The validity of the definition of a formal QI project needs to be established. More research to identify the barriers to successful QI implementation at LHDs is also needed.

Local public health systems and the incidence of sexually transmitted diseases

OBJECTIVES

We examined the associations of local public health system organization and local health department resources with county-level sexually transmitted disease (STD) incidence rates in large US health jurisdictions.

METHODS

We linked annual county STD incidence data (2005-2008) to local health department director responses (n = 211) to the 2006 wave of the National Longitudinal Study of Local Public Health Systems, the 2005 national Local Health Department Profile Survey, and the Area Resource File. We used nested mixed effects regression models to assess the relative contribution of local public health system organization, local health department financial and resource factors, and sociodemographic factors known to be associated with STD incidence to county-level (n = 307) STD incidence.

RESULTS

Jurisdictions with local governing boards had significantly lower county-level STD incidence. Local public health systems with comprehensive services where local health departments shoulder much of the effort had higher county-level STD rates than did conventional systems.

CONCLUSIONS

More integration of system partners in local public health system activities, through governance and interorganizational arrangements, may reduce the incidence and burden of STDs.

The economic, institutional, and political determinants of public health delivery system structures

OBJECTIVES

A typology of local public health systems was recently introduced, and a large degree of structural transformation over time was discovered in the systems analyzed. We present a qualitative exploration of the factors that determine variation and change in the seven structural configurations that comprise the local public health delivery system typology.

METHODS

We applied a 10-item semistructured telephone interview protocol to representatives from the local health agency in two randomly selected systems from each configuration--one that had maintained configuration over time and one that had changed configuration over time. We assessed the interviews for patterns of variation between the configurations.

RESULTS

Four key determinants of structural change emerged: availability of financial resources, interorganizational relationships, public health agency organization, and political relationships. Systems that had changed were more likely to experience strengthened partnerships between public health agencies and other community organizations and enjoy support from policy makers, while stable systems were more likely to be characterized by strong partnerships between public health agencies and other governmental bodies and less supportive relationships with policy makers.

CONCLUSIONS

This research provides information regarding the determinants of system change, and may help public health leaders to better prepare for the impacts of change in the areas discussed. It may also help those who are seeking to implement change to determine the contextual factors that need to be in place before change can happen, or how best to implement change in the face of contextual factors that are beyond their control.

What is the role of free clinics in the safety net?

BACKGROUND

Free clinics play an important role in the safety net but little is known about what factors drive their existence within a given community. The anecdotal literature suggests that they exist due to growing numbers of uninsured and a lack of affordable care.

OBJECTIVE

To determine whether unmet needs explain the existence of free clinics.

MATERIALS AND METHODS

The relationship between demographics, Medicaid policy, and ambulatory safety-net care on the geographical distribution of all known free clinics (n=1007) across all metropolitan statistical areas (n=361) in the United States is investigated cross sectionally. Drawing from numerous secondary data sources and an original dataset of all known free clinics, a negative binomial model is used to examine whether free clinic prevalence is higher in communities with larger proportions of uninsured patients, poor adults, and African Americans and is lower in communities with greater availability of federally qualified health centers (FQHCs), FQHC look-alikes, and health departments, and more generous Medicaid eligibility for working parents and Medicaid beneficiary/provider payment levels.

RESULTS AND DISCUSSION

None of the demographic variables has a positive, statistically significant relationship to the number of free clinics in a metropolitan statistical area. However, the number of FQHC grantees per 10,000 uninsured individuals [incidence rate ratios (IRR)=0.69, P<0.05], the number of FQHC look-alike sites per 10,000 uninsured individuals (IRR=0.46, P<0.05), Medicaid beneficiary payments (IRR=0.9998, P<0.05), and Medicaid eligibility levels (IRR=0.998, P<0.10) are negatively associated with the number of free clinics. Thus, free clinics seem to respond to particular gaps left by safety-net providers and Medicaid but do not seem to respond to direct need.

Creating an online "promising practices" clearinghouse for pandemic influenza

This article describes efforts to create, share, and sustain an online clearinghouse of expert-reviewed "promising practices" in pandemic influenza preparedness from September 2006 to December 2008. This project involved six activities: (1) determining focus areas, (2) defining a promising practice, (3) collecting practices, (4) establishing an expert-review process for accepting practices, (5) disseminating the practices, and (6) evaluating the project. By December 31, 2008, materials and descriptions for 181 expert-reviewed practices had been posted in a public online database. Practices were available in four areas: models for care, communication, mitigation, and at-risk groups. The database has been used by international agencies and a variety of U.S. organizations. The challenges and constraints facing the U.S. public health system underscore the need to maximize resources. We believe that the Promising Practices Project demonstrates a useful approach in pandemic preparedness and response and may serve as a valuable model for other areas of public health.

Public health systems: a social networks perspective

OBJECTIVE

To examine the relationship between public health system network density and organizational centrality in public health systems and public health governance, community size, and health status in three public health domains.

DATA SOURCES/STUDY SETTING

During the fall and the winter of 2007-2008, primary data were collected on the organization and composition of eight rural public health systems.

STUDY DESIGN

Multivariate analysis and network graphical tools are used in a case comparative design to examine public health system network density and organizational centrality in the domains of adolescent health, senior health, and preparedness. Differences associated with public health governance (centralized, decentralized), urbanization (micropolitan, noncore), health status, public health domain, and collaboration area are described.

DATA COLLECTION/EXTRACTION METHODS

Site visit interviews with key informants from local organizations and a web-based survey administered to local stakeholders.

PRINCIPAL FINDINGS

Governance, urbanization, public health domain, and health status are associated with public health system network structures. The centrality of local health departments (LHDs) varies across public health domains and urbanization. Collaboration is greater in assessment, assurance, and advocacy than in seeking funding.

CONCLUSIONS

If public health system organization is causally related to improved health status, studying individual system components such as LHDs will prove insufficient for studying the impact of public health systems.

State funding for local public health: observations from six case studies

The purpose of this study is to describe state funding of local public health within the context of state public health system types. These types are based on administrative relationships, legal structures, and relative proportion of state funding in local public health budgets. We selected six states representing various types and geographic regions. A case study for each state summarized available information and was validated by state public health officials. An analysis of the case studies reveals that the variability of state public health systems--even within a given type--is matched by variability in approaches to funding local public health. Nevertheless, some meaningful associations appear. For example, higher proportions of state funding occur along with higher levels of state oversight and the existence of local service mandates in state law. These associations suggest topics for future research on public health financing in relation to local accountability, local input to state priority-setting, mandated local services, and the absence of state funds for public health services in some local jurisdictions.
